This 8-channel EEG/ECG/EMG/EOG data acquisition chip shares its analogue circuitry with its predecessor Cerebro v3 while its digital signal processing has been extended. It provides full reconstruction of the DC-connected signal, mains interference cancellation, high-pass and low-pass filtering (if desired) and a configurable output data-rate between 200 and 4k samples per second. Furthermore, a compressed sensing (CS) encoder optimized for ECG signals is included to dramatically reduce the data-rate in telecare applications.
The logo is inspired by Homer Simpson, and depicts a widely available picture from the internet. This ties to the fact that the original Cerebro chip had a brain as its logo. This in turn was partly due to the fact that the chip was meant (among others) for EEG measurements.
This is the fourth generation chip in the series after:
